PDF bleed & trim check
The geometry a press cuts by — validated before the press does.
What it checks
- TrimBox presence — a press cannot guess where to cut; a missing TrimBox is a finding, not a shrug
- Page-box nesting: Trim, Bleed, and Art boxes must sit correctly inside the MediaBox
- Page-size and geometry consistency across the document
- Runs with the rest of the print checks (PDF/X claims, resolution, ink coverage) in one pass
FAQ
What is bleed and why do printers reject files without it?
Bleed is artwork extending past the trim line so cutting tolerance never leaves white slivers. Files whose geometry doesn’t declare trim/bleed correctly force manual prepress intervention — or get bounced.
What is the TrimBox exactly?
The PDF page box that declares the finished page size after cutting. Presses and imposition software key on it; PDF/X requires the geometry to be declared unambiguously.
